The role of detritivores in the conversion of allochthonous
leaf material in two small streams in the Cascade Range of Oregon
was studied. Their importance in relation to other consumers was
estimated from emergence and benthic standing crop data.
Ingestion rates and efficiencies of utilization of bigleaf maple
(Acer macrophyllum)...
The purpose of the study was to provide quantitative information on the utilization and processing of leaves and needles by several species of caddisfly larvae.
Field and laboratory studies were conducted on three species of Lepidostoma Rambur (Lepidostomatidae), from Willamette Valley and Cascade Mountain streams, and on Clistoronia magnifica (Banks)...
Riparian zone vegetation can influence terrestrial and aquatic food webs through variations in the amounts, timing, and nutritional content of leaf and other litter inputs. Differences in vegetation composition and density, as well as riparian topography, may modulate the strength and quality of these inputs. Changes in inputs to small...
Riparian-zone vegetation can influence terrestrial and aquatic food webs through variation in the amount, timing, and nutritional content of leaf and other litter inputs. We investigated how riparianforest community composition, understory density, and lateral slope shaped vertical and lateral litter inputs to 16 streams in the Oregon Coast Range. Riparian...
This study examined the effect of increasing in-channel leaf standing stocks on hydrologic transient storage and nutrient retention in a Mediterranean mountain stream. A flood at the end of the leaf fall period provided the opportunity to examine the effect of abrupt removal of much of the leaf material. Twenty-one...
This study explored how selected input and redistribution processes affect the amount and arrangement of in-stream wood within the 64 km2 Lookout Creek watershed in the Andrews Forest, western Cascade Range, Oregon. A longitudinal inventory of in-stream wood was conducted over approximately 20 km of stream length in 2nd to...
On average, the water column of Lake Superior is undersaturated with respect to dissolved oxygen and supersaturated with respect to carbon dioxide during the summer-stratified period. On the basis of temporal changes in water column dissolved oxygen, we calculate rates of oxygen consumption that range from 0.19 to 0.75 mmol...
